The working principle of the existing vacuum fish sucking machine, such as the Chinese patent with the patent publication number of CN110269050A, is different from that of a fish sucking machine, and the main working principle of the three-dimensional intelligent fish fry distribution system is that a fish-water mixture is communicated with a fish storage tank through a fish conveying pipeline, the pressure in the fish storage tank is reduced under the negative pressure action of a vacuum pump, and then the fish-water mixture is sucked into the fish storage tank through the fish conveying pipeline. And (3) inflating the fish storage tank after the fish-water mixture in the fish storage tank reaches a set amount, discharging the fish and water in the fish storage tank, and storing the fish into a fish storage tank at the rear end after the fish and the water are separated.
At present, most of vacuum fish suction machines adopt the technical scheme, but have shortcomings in practice. For example, when the vacuum fish sucking machine is used for catching fish fries or performing pond replacement operation, the growth state of the fish is adversely affected in the whole fish sucking process. Briefly, for example, before and during the fish sucking process, the fish tends to move violently, so that the demand of the fish for oxygen increases in a short time, and when the fish storage tank is vacuumized, the dissolved oxygen in the water in the fish storage tank theoretically decreases, the larger the volume of the fish storage tank is, the longer the fish-water mixture remains in the fish storage tank (usually, the outlet of the fish storage tank needs to be opened after the fish-water mixture in the fish storage tank reaches a set amount), and the more the oxygen content in the water decreases, which all are adverse to the growth of the fish.

Correspondingly, a suction one-way valve 25 is arranged at the communicating position of the first pipeline 23 and the fish storage tank 4, the conduction direction of the suction one-way valve 25 is set from the inside of the fish storage tank 4 to the first pipeline 23, namely the first pipeline 23 can only be completed by the inflation tube 21 when the first pipeline 23 inflates the inside of the fish storage tank 4.
In further detail, an electrically controlled flow regulating valve 26 is arranged between the oxygen increasing device 22 and the plurality of inflation tubes 21, and the electrically controlled flow regulating valve 26 is in control connection with the controller 2. The controller 2 is connected with a temperature detection device for detecting the water temperature in the fish-water mixture, the temperature detection device detects the water temperature and outputs a temperature detection signal to the controller 2, and the controller 2 receives and responds to the temperature detection signal to control the flow of the electric control flow regulating valve 26. The technical scheme can adjust the oxygen increasing amount of the oxygen increasing device 22 according to different water body temperatures, and maintain the stability of the oxygen content in the water body.
In order to facilitate the maintenance of the interior of the fish storage tank 4, at least one maintenance opening 27 is formed in the tank body of the fish storage tank 4, and it should be understood that the maintenance opening 27 is in a closed locking state when the fish sucking machine is in a working state.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
